openfire插件 servlet开发

1、首先建一个SampleServlet类，（名字随意。）继承 HttpServlet

package com.maojd.test;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class SampleServlet extends HttpServlet{    private static final long serialVersionUID = -5404916983906926869L;    /* @Override    public void init() throws ServletException {        super.init();    }*/        @Override    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {       // super.doGet(request, response);        response.setContentType("text/plain");        PrintWriter out = response.getWriter();        System.out.println("请求SampleServlet GET Method mao");        out.print("请求SampleServlet GET Method mao");        out.flush();    }     @Override    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        //super.doPost(request, response);        this.doGet(request, response);                response.setContentType("text/plain");        PrintWriter out = response.getWriter();        System.out.println("请求SampleServlet GET Method mao");        out.print("请求SampleServlet POST Method mao");        out.flush();    } }

2、配置servlet的路径

a) Web目录下建 WEB-INF

b)WEB-INF下建一个 web-custom.xml文件，配置对应servlet映射信息。这个文件相当于普通web工程的web.xml

web-custom.xml内容如下：

<?xml version='1.0' encoding='ISO-8859-1'?><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app>    <!-- Servlets -->    <servlet>        <servlet-name>SampleServlet</servlet-name>        <servlet-class>com.maojd.test.SampleServlet</servlet-class>    </servlet>    <!-- Servlet mappings -->    <servlet-mapping>        <servlet-name>SampleServlet</servlet-name>        <url-pattern>/servlet</url-pattern>    </servlet-mapping></web-app>

说明：（重要！！！！！！）

Servlet的配置 url必须全部小写。有一个大写字母则找不到对象的servlet。

配置多个servlet,和单个方法一样。配置多个servlet 和 servlet-mapping即可。

3、在plugin.xml文件中配置JSP页面显示位置

<adminconsole>   <tab id="tab-server">          <sidebar id="sidebar-server-settings">              <item id="sample-service" name="Sample Service maojd" url="myplugin-demo1.jsp" description="Click is trigger sample plugin" />          </sidebar>    </tab></adminconsole>

备注：item标签中的id是自己定义的，要保证唯一，不能与其他的插件冲突，因此我们可以将这个ID的命名规则设为（插件名-页面）。JSP页面会根据这个ID来确定左侧菜单栏的显示位置。

4、创建JSP页面

Web目录下建jsp页面 myplugin-demo1.jsp，命名规范：插件名-页面名.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html>  <head>    <title>hello world： 你好openfire</title>    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">    <meta name="pageID" content="sample-service"/>  </head>    <body>    <h3>hello world jsp!! <a href="/plugins/myplugin/servlet">SampleServlet</a></h3>    <div class="jive-contentBoxHeader">jive-contentBoxHeader</div>    <div class="jive-contentBox">jive-contentBox</div>        <div class="jive-table">        <table cellpadding="0" cellspacing="0" border="0" width="100%">            <thead>                <tr>                    <th>&nbsp;sss</th>                    <th nowrap>a</th>                    <th nowrap>b</th>                </tr>            </thead>            <tbody>                <tr>                    <td align="center">asdf</td>                    <td align="center">asdf</td>                    <td align="center">asdf</td>                </tr>                <tr class="jive-even">                       <td align="center">asdf</td>                    <td align="center">asdf</td>                    <td align="center">asdf</td>                </tr>                <tr class="jive-odd">                       <td align="center">asdf</td>                    <td align="center">asdf</td>                    <td align="center">asdf</td>                </tr>             </tbody>        </table>    </div>  </body></html>

备注：Jsp需要注意：<meta name="pageID" content="sample-service"/>

PageID固定就这样不变， Sample-service可以随便，但是一定要和标题对应ID保持一致（top 导航id和左侧导航id对应），一般是和plugin.xml对应。
